Desaad is a slick torturer working for Darkseid and a villain in the Superman series.
Desaad was once an innocent New God from New Genesis until he was corrupted by Darkseid. Darkseid lied to Desaad that the boy's bird was killed by his cat. Angered, Desaad was tricked into killing the cat to avenge his pet bird. After avenging his bird, Desaad went to Apokolips to become Darkseid's sadistic torturer & majordomo. He helped Darkseid kill Drax and take control of Apokolips. Later, Desaad worked with Bruno Mannheim and the Intergang to meet Darkseid's crimes on Earth.
Kalibak preoffered to kill Superman himself but Darkseid refused. Seeing this, Desaad manipulated Kalibak into going to Earth to kill Superman, claiming if he succeeded, Darkseid would accept Kalibak as his son. Kalibak agreed and went to Earth to fight the Man of Steel. Darkseid later learned that Kalibak left for Earth and punished him for his failure.
